Mojang Drops Toss Lab Physics Playground for Creators

The official sample turns the chaotic new entity behaviors from Chaos Cubed into a side-scrolling puzzle game that shows exactly how bouncy rubber, drifting cotton, and sticky globs can power custom maps right now.

Most new Minecraft features get announced with fanfare then left for the community to figure out. Toss Lab flips that script. Released this week, it is a complete single-player puzzle experience built specifically to showcase the entity physics Mojang added in the Chaos Cubed drop.

You play as a little character with a satchel full of weird objects. Each one behaves according to the new components: bounciness, friction modifiers, air drag, knockback rules, and more. A rubber ball ricochets like it is possessed. A stone block drops like it owes rent. Cotton drifts lazily. Ice slides. Glue sticks. The goal is to toss the right object to the right spot to open paths, trigger switches, or fill gaps.

Why this matters right now

The sample is not just a demo. It comes with the full source in the official Minecraft Samples repo on GitHub, updated documentation for the new physics fields, and a dedicated tour on the Minecraft Learning Portal. Creators can rip it apart today and start building maps that use these behaviors instead of fighting them.

This is the fastest path from Mojang announcement to usable creator tool we have seen in the four-drops-per-year era. Instead of vague patch notes, players and map makers get a playable proof of concept that makes the physics feel intentional and fun.

If you are tired of the same old command-block contraptions or want to see what real physics-driven gameplay looks like in Bedrock, download Toss Lab. The puzzles are short but the implications for custom content are not. Expect to see these bouncing, drifting, sticking mechanics show up in minigames and adventure maps within weeks.

  • Free download from the Minecraft Samples GitHub repository
  • Demonstrates bounciness, air_drag_modifier, friction, and knockback on real objects
  • Single-player side-scroller that doubles as a creator tutorial
  • Ties directly into the 1.26.20 and 1.26.30 updates from the latest game drop
  • Includes guided learning-portal tour for new creators

Toss Lab shows what happens when you give every object its own personality and then ask players to solve problems with nothing but a good throw.
